Implementations

impl<'mir, 'tcx> Qualifs<'mir, 'tcx>

pub fn indirectly_mutable(
    &mut self,
    ccx: &'mir ConstCx<'mir, 'tcx>,
    local: Local,
    location: Location
) -> bool

pub fn needs_drop(
    &mut self,
    ccx: &'mir ConstCx<'mir, 'tcx>,
    local: Local,
    location: Location
) -> bool

Returns true if local is NeedsDrop at the given Location.

Only updates the cursor if absolutely necessary

pub fn has_mut_interior(
    &mut self,
    ccx: &'mir ConstCx<'mir, 'tcx>,
    local: Local,
    location: Location
) -> bool

Returns true if local is HasMutInterior at the given Location.

Only updates the cursor if absolutely necessary.

fn in_return_place(
    &mut self,
    ccx: &'mir ConstCx<'mir, 'tcx>,
    error_occured: Option<ErrorReported>
) -> ConstQualifs

Trait Implementations

impl<'mir, 'tcx> Default for Qualifs<'mir, 'tcx>

fn default() -> Qualifs<'mir, 'tcx>

Returns the “default value” for a type.
